Mikawa Nagura 1337g

Mikawa Nagura are Tuff stones, a type of igneous rock formed from lithified volcanic ash. Mined in Aichi prefecture starting 700 years ago, they have been used in traditional Japanese sword polishing progressions. The mine has been closed since the 1970s.

We receive the stones from the wholesaler with rough chisel marks on both sides, and flatten them in our workshop. Although we have made a good effort to provide a flat surface for usage, we strongly recommend end users flatten the sharpening surface once more with a diamond plate.

This stone has a dent from the chiselling process. However, there is still a large surface available for use. Nevertheless, due to the shape, the price has been reduced to 1.12HKD/g. Functionality and performance is not affected by the shape of the stone.
